tib. I 3-3. tib. II an anterior lateral, a pair at distal end, and 
one behind, below; met. I and II 2-2. 
Cephalothorax ratber low with cephalic part a little in¬ 
clined, and thoracic part flat in first half. Front eyes in a 
slightly curved row, moderately large, the middle less than twice 
the lateral. Eye-region equally wide in front and behind. 
Second row halfway between the others, third row narrower 
than the cephalothorax. Sternum oval, a little narrowed and 
truncated in front, labium longer than wide. Coxae I separated 
by width of labium. 
When dry the integument is dark brown, blackish in eye-reg¬ 
ion, with a thin covering of white hairs, and a whitish stripe 
on the middle of the abdomen. Under alcohol the pattern comes 
out more distinctly, the spider being gray with a lighter longi¬ 
tudinal band on the abdomen, from base to apex, which is edged 
with a series of short, pure white bars, outlined in black. On 
the posterior sides are some oblique whitish bars. The first 
legs are brown, with incomplete dark rings, the others yellow, 
with dark bands. The clypeus has long white hairs. Mr. Banks 
has two examples from Alberquerque, Hew Mexico.
